PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 334,227, dated January12, 1886.

Application filed November 13, 1855. Serial-No. $2,728.

To @ZZ whom t may concern:

Beit known that I, WILLIAM IIELLEM, a citizen of the United States, anda resident of Allentown, in the county of Allegany and State of NewYork, have invented certain new and useful Improvements inTube-Wrenches; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in 1o the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure l is a perspective View of myimproved tubing and pipe tongs, showing the same open for adjustmentupon the tubing. Fig. 2 is atop view showing the device closed and inposition for operation upon a tube, which is shown in section. Fig. 3 isa longitudinal horizontal sectional View of the device as shown in Fig.2, and Fig. 4 is a longitudinal vertical sectional view of the same.

This invention relates to an improved tubewrench adapted particularlyfor the manipulation of tubes when they are being set in position inoil-wells, salt-wells, and other deep wells; and it has for its objectto pro-- vide a device of this class which shall possess superioradvantages in point of simplicity,

3o durability, and general eftieiency.

Vith these ends in view the invention consists in the improvedconstruction of the said wrench, which will be hereinafter fullydescribed, and particularly pointed out in the 5 claims.

In the drawings hereto annexed, A and B designate the two semicircularjaws of my improved wrench, the rear ends of which are connected bymeans of a hinge, C, the central leaf of which, D, is fitted looselybetween the two outer leaves, E E, as will be seen in Fig. l of thedrawings, so as to enable the jaws to vibrate slightly with relation toeach other, for the purpose which will be herein- 4 5 after set forth.

The jaw A is provided at its rear end with a rearwardly-extending shank,F, having a shoulder, G, and terminating in aplate, H, to which ispivoted a handle, I, the front (No model.)

end of which terminates in a triangular plate, 5o J, having an inclinedor diagonal front side,

K, facing the shoulder G. The rear end of thejaw B has adiagonally-extending arm, L, adapted to t loosely between the shoulder Gand the plate J, as will be seen in Fig. 2 of 55 the drawings.

The inner concave sides of the jaws A and B are provided with triangulardie-plates M M, partly embedded therein, but having projecting sharprear edges, N N, adapted to en- 6o gage the tubing which is to beoperated upon by the wrench.

The operation of this invention will be readily understood from theforegoing description, taken in connection with the drawings heretoannexed.

In order to adj ust the wrench upon the tubing, it is opened, as shownin Fig. l, when it may be readily slipped into position and closed, thusplacing the arm L in the position shown 7o in Fig. 2.

By working the lever or handle I in either direction the plate .I willbe caused to bear against the said arm L, thus forcing the jaws togetherand causing one of the dies M to. engage the tube, which may thus beturned in the direction in which the lever I is moved. The lever may bemoved and the device be operated in either direction.

The arm L is slightly beveled on its under 8o side, at its end, toenable it to pass over the plate J, and the loose hinge, to whichreference has been made, also serves to facilitate the opening orclosing of the jaws.

Having thus described my invention, I claim S5 and desire to secure byLetters Patent of the United States- I. In a pipe-wrench, thecombination of the jaw A, having a shank provided with a shoulder, andhaving a pivoted handle or lever 9o provided with a triangular plate,with the jaw B, hinged to the jaw A and having the arm L, substantiallyas and for the purpose set forth.

2. In a pipe-wrench, the combination of the jaws A and B, connected by ahinge which admits of a vibrating motion of the said jaws with relationto each other, the shank F, ex-

tending from the jaw A and having shoul- In testimony that I claim theforegoing as der G and plate H, the pivoted handle I, my own I havehereunto afixed my signature having plate J, the arm L, extending fromin presence of' two witnesses.
